TomEE and MySql - query don't returns any results

[beginner_user <ka...@hotmail.com>]

Hi,

I am using TomeEE + MySql and i have problem because function
createNamedQuery don't returns any results. I thought that problem is with
my
entityManager but i checked in debugMode and is injected.

This is my code:

User Entity:

package pl.gsite.db.model;

import java.io.Serializable;
import javax.persistence.Basic;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.NamedQueries;
import javax.persistence.NamedQuery;
import javax.persistence.Table;
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Size;
import javax.xml.bind.annotation.XmlRootElement;


@Entity
@Table(name = "user")
@XmlRootElement
@NamedQueries({
    @NamedQuery(name = "User.loginAndPassword", query = "SELECT u FROM User
u WHERE u.login = :login and u.password = :password"),    
    @NamedQuery(name = "User.findAll", query = "SELECT u FROM User u"),
    @NamedQuery(name = "User.findById", query = "SELECT u FROM User u WHERE
u.id = :id"),
    @NamedQuery(name = "User.findByLogin", query = "SELECT u FROM User u
WHERE u.login = :login"),
    @NamedQuery(name = "User.findByPassword", query = "SELECT u FROM User u
WHERE u.password = :password")})
public class User implements Serializable {
    private static final long serialVersionUID = 1L;
    @Id
    @Basic(optional = false)
    @NotNull
    @Column(name = "id")
    private Integer id;
    @Size(max = 100)
    @Column(name = "login")
    private String login;
    @Size(max = 100)
    @Column(name = "password")
    private String password;

    public User() {
    }

    public User(Integer id) {
        this.id = id;
    }

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getLogin() {
        return login;
    }

    public void setLogin(String login) {
        this.login = login;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    @Override
    public int hashCode() {
        int hash = 0;
        hash += (id != null ? id.hashCode() : 0);
        return hash;
    }

    @Override
    public boolean equals(Object object) {
        // TODO: Warning - this method won't work in the case the id fields
are not set
        if (!(object instanceof User)) {
            return false;
        }
        User other = (User) object;
        if ((this.id == null && other.id != null) || (this.id != null &&
!this.id.equals(other.id))) {
            return false;
        }
        return true;
    }

    @Override
    public String toString() {
        return "pl.gsite.db.model.User[ id=" + id + " ]";
    }
    
}


My ManagedBean:

@Named(value = "loginRequest")
@RequestScoped
public class LoginRequest {
   @PersistenceContext(unitName = "gsitePU")
   private EntityManager em;
   
   @Inject
   private LoggedUserBean loggedUserBean;
   private String login;
   private String password;
    
    public LoginRequest() {
    }
    
    public String authentication() {        
        try {
            List<User> uList = new ArrayList<User>();            
            TypedQuery qq = em.createNamedQuery("User.findAll", User.class);
            uList = qq.getResultList(); // <-- returns empty list
            TypedQuery<User> query =
em.createNamedQuery("User.loginAndPassword",
User.class).setParameter("login", login).setParameter("password", password);    
            User u = query.getSingleResult(); // <-- throws an
NoResultException
            this.loggedUserBean.setLoggedUser(u);            
        }
        catch(NoResultException e) {
            e.printStackTrace();
        }
        
       return "index";
    }

    /**
     * @return the login
     */
    public String getLogin() {
        return login;
    }

    /**
     * @param login the login to set
     */
    public void setLogin(String login) {
        this.login = login;
    }

    /**
     * @return the password
     */
    public String getPassword() {
        return password;
    }

    /**
     * @param password the password to set
     */
    public void setPassword(String password) {
        this.password = password;
    }
}
